"An obstacle!" I echoed, forgetting my headache. "I can't understand that, if—forgive me—if you're free."

"I am free," the girl said. "Free in the way you mean. There's no man in the way. The obstacle is—a woman."

"Pooh!" I cried, my heart lightened. "I wouldn't let a woman stand between me and the man I loved, especially if he needed me as much as—as——"

"You needn't mind saying it. Of course you know as well as I do that we're talking about Ralston Murray. And I believe he does need me. I could make him happy—if I were always near him—for the few months he has to live."

"He would have a new lease of life given him with you," I ventured.

The girl shook her head. "He says that the specialists gave him three months at the most. And twelve days out of those three months have gone already, since he left California."

For an instant a doubt of her shot through me. Ralston Murray had been a get-rich-quick oil speculator, so I had heard, anyhow, he was supposed to be extremely well off. Besides, there was that lovely old place in Devonshire, of which his widow would be mistress. I knew nothing of Rosemary Brandreth's circumstances, and little of her character or heart, except as I might judge from her face, and voice, and charming ways. Was I wrong in the judgment I'd impulsively formed? Could it be that she didn't truly care for Murray—that if she married him in spite of the mysterious "obstacle," it would be for what she could get?

Actually I shivered as this question asked itself in my mind! And I was ashamed of it. But her tone and look had been strange. When I tried to cheer her by hinting that Murray's lease of life might be longer because of her love, she had looked frightened, almost horrified.

For the first time I deliberately tried to read her soul, whose sincerity I had more or less taken for granted. I stared into her eyes through the green dusk which made us both look like mermaids under water. Surely that exquisite face couldn't mask sordidness? I pushed the doubt away.

"All the more reason for you to make radiant the days that are left, if you're strong enough to bear the strain," I said. And Rosemary answered that she was strong enough for anything that would help him. She would tell Ralston, she added, that she had asked my advice.
